    • 2017-2023 NOAA East Coast Historical InSAR Data

    Metadata Updated: March 13, 2026

    Dewberry contracted TRE Altamira Inc (TREA) for a historical InSAR analysis of ground displacement over the East Coast of the United States of America (U.S.A.), for the National Oceanic and Atmospheric Administration (NOAA). The area of interest (AOI) includes the major coastal cities and coastal plains and covers over 500,000 km2 (193,000 mi2).

    TREAs proprietary SqueeSAR algorithm was used to process Sentinel-1 (SNT) satellite imagery acquired between January 2017 and July 2023 and the results were calibrated using the NOAA's CORS GNSS (Global Navigation Satellite System) network for the generation of vertical InSAR (SAR Interferometry) measurements.
